UNI-T UT312A Vibration Tester – Handheld Industrial Vibration Measurement Tool
The UNI-T UT312A Vibration Tester is a professional handheld instrument for monitoring the vibration condition of machinery and equipment. It accurately measures key vibration parameters including acceleration, velocity, and displacement, helping technicians detect imbalance, misalignment, bearing wear, and other mechanical issues before they lead to failure. This versatile tester is ideal for use in industrial maintenance, power generation, manufacturing, petrochemical, and mechanical engineering environments.
Key Features
- Measures vibration acceleration (PEAK), vibration velocity (RMS), and vibration displacement (P-P) for comprehensive equipment analysis.
- Dual frequency modes for high- and low-frequency acceleration measurement.
- 2.4″ TFT color display with automatic screen rotation for easy viewing.
- Rechargeable lithium battery with USB-C charging for portable use.
- Data hold function captures measurement values.
- Flashlight for measurements in low-light environments.
- Automatic power-off and low battery indication for energy saving.
- Multiple probes support (long and short probes), plus a magnetic attachment accessory (UT312A only) for flexible measurement.
